add-classpath stopped working with ns:import?

[Steffen Glückselig]

I just updated from SVN resulting in some code of mine no longer
working:


(add-classpath "file:///C:/clojure/scripts/metadata-
extractor-2.3.1.jar")

(ns images.date-sorter
(:import (javax.swing JFileChooser))
(:import (java.io File FilenameFilter))
(:import (java.text SimpleDateFormat))
(:import (com.drew.imaging.jpeg JpegMetadataReader)))
(:use [clojure.contrib.seq-utils :only (group-by)]))



I get:

Exception in thread "main" java.lang.ClassNotFoundException:
com.drew.imaging.jpeg.JpegMetadataReader(image-categorizer.clj:5)

Did something break or was there a chance on purpose - or am I doing
something wrong?

There are changes in the latest SVN which cause
problems with add-classpath. The official fix is:
use the release.

A second comment: The setup you described
indicates, that you use add-classpath in a stable
situation. This is strongly discouraged. The official
use case for add-classpath is to test a library in an
already running repl. In your case the "usual way"
is to setup all libraries before starting Clojure.

That said: YMMV.
